A clean (read safe) pool is a necessity. Learn to do it yourself. Once you know all the steps you can delegate but you will know if the care is adequate.
In this country everybody is an expert in everything and can do anything. (Ok, slight exaggeration). Consistency is rare here (not an exaggeration)
Lotsa info on the internet,- pools need brushing, vacuuming, chemical testing and balancing of chemicals . Not an onerous job for you. Then, if you can find someone who comes highly recommended you will know what he has to do.
Trust yourself to have a safe pool!
